1 General

1.1 Introduction

This specification describes the EDI model to be used when handling, for instance, a change of Gas Supplier in the Danish gas market. It must be used by all players having a role in this communication. The specification is based on the North European ebIX standard and has been adapted to the Danish market model and the existing Danish EDI communication in the gas market.

Metering Point

With reference to the Rules for Gas Distribution, version 3, the use of EDI communication mandatory for all commercial players in the gas market.

1.2 Documentation principle

The documentation has been structured so as to simplify the mapping and documentation of new scenarios as well as changing existing ones. Readers with a business background need not focus on technical details and technicians not on business aspects.

The documentation, which is available in Danish and English, is divided into five parts:

 Business scenarios for EDI communication in the gas market

 Danish Business Transactions for the Gas Market

 Danish Message Implementation Guides

 EDI communication (Regulation F)

 Danish product code list.

In case of any discrepancy between the above-mentioned documentation, Busi- ness scenarios for EDI communication in the gas market will at all times be the primary reference. In particular, discrepancies may occur between this document and the transaction examples given in Danish Business Transactions for the Gas Market.

Business scenarios for EDI communication in the gas market provides a de- scription of business rules and procedures for the practical handling of change of supplier and other business scenarios. The target group consists of superusers and others active in the Danish gas sector. The document has been prepared in the form of so-called sequential diagrams providing a general illustration of the data exchanged between the individual players and the points in time of the exchange.

(13)

The technical content of the data exchanges is not specified in any detail, and reference is only made to relevant parts of Danish Business Transactions for the Gas Market. As a consequence, the need for new or adjusted business scenarios is more readily identified and can be more easily implemented, ie market players will be less restricted by technical obstacles. Documentation can be found at www.gasmarked.dk.

Danish Business Transactions for the Gas Market specifies the use in Denmark of the European ebIX model. This part of the documentation, which is targeted at IT suppliers, specifies how the IT systems should operate in relation to data exchange in the market. The documentation is presented in the form of activity diagrams for the IT systems' handling of the individual EDI messages and associated data models for the individual situations. All business transactions are autono- mous and independent of other business transactions. They are used as 'building blocks' in the business scenarios. A business transaction developed for a given business scenario can be re-used in other business scenarios. The relevant documentation can be found at www.gasmarked.dk .

Danish Message Implementation Guide describes the use in Denmark of a given EDIFACT message, eg UTILMD. The basis of the description is the European ebIX Message Implementation Guide, the Danish version of which shows the concrete Danish definition of the attributes applied and the values and codes allowed. The documentation can be found at www.gasmarked.dk.

EDI communication (Regulation F) applies to the electricity and gas markets and contains a specification of all documentation common to the exchange of EDI messages, ie issues such as addressing, opening hours, communication protocol and error handling at the individual levels. The documentation applies to all exchanges of data via EDI communication, for instance when metered data are implemented in a revised form and in the case of a change of supplier in the electricity or gas sector.

The documentation is used as supplement to ebIX’ Common rules and recom- mendations, available at www.ebix.org, and therefore contains primarily the Dan- ish rules that are not included in the ebIX recommendation. Approval is granted by the organisation(s) responsible for the business rules, eg the transmission system operator (TSO) and projects for the implementation of new market rules. The documentation can be found at www.gasmarked.dk.

The Danish product code list applies to the electricity and gas markets, containing all the common Danish product codes. The product code list can be found on www.energinet.dk.

(14)

1.3 The basis of the specification

This EDI specification, which has been prepared by Energinet.dk and the natural gas distribution companies in Denmark, is based on Rules for Gas Distribution, which are available on www.gasmarked.dk.

In respect of data exchange, the specification is based on the following docu- ments, which can be accessed at or downloaded from www.ebix.org :

- ebIX model for customer switching, version 0.8 A of 25 September 2003.

- Implementation guide for Utility Base Data Message (UTILMD), version 5.0 B.

- Implementation guide for metered services consumption report (MSCONS), version 2.4D.

- Implementation guide for Application error and acknowledgement message (APERAK), version 2.4B.

- ebIX code list: www.ebix.org

1.4 Other communication

Other communication is communication by letter, telefax or email. The Distribu- tion Company, the Gas Supplier and the transmission system operator must use other communication in the following cases:

 In situations where EDI communication is not used. Each business scenario specifies when other communication is or can be used as well as the applicable deadlines.

 In emergency situations where it is technically impossible to use EDI communication. For most business scenarios, emergency procedures have been established that must be complied with by the Distribution Company, the Gas Supplier and the transmission system operator. These emergency procedures are described in section 4, which also includes a form to be completed in the event of a change of supplier.

1.5 Definitions

The business terms used in the gas sector and in this guide are defined below.

(15)

Business Day

Business Days are Monday through Friday with the exception of holidays etc. as specified in the Business Day calendar on Energinet.dk’s website

(www.energinet.dk). The definition is the same for the electricity and the gas markets.

Bio Natural Gas (BNG)

Bio Natural Gas is bio gas which has been upgraded with a view to fulfilling the quality specifications for natural gas in the Danish Gas System. BNG can be physically transported in the Danish Natural Gas System through the Distribution Network.

BNG Transition Point

A BNG Transition Point is a virtual point facilitating the supply of BNG into the Danish Natural Gas System. Each BNG Transition Point will be assigned a GLN (Global Location Number).

Distribution Company

Distribution Company is any natural or legal person authorised to carry out natural gas distribution.

Market Share Value of the Distribution Area

The Market Share Value of the Distribution Area is the sum of the Market Share Values of the Metering Pointof all the Non-Daily Read Metering Points in a distribution area.

Relocation

Relocation is the situation when a consumer vacates a specific Metering Point and/or a new consumer moves to the same Metering Point.

Public Supply Obligation Company

Public Supply Obligation Company is a Gas Supplier who in accordance with the Danish Natural Gas Supply Act is responsible for supplying gas to consumers and potential consumers in areas designated for natural gas supply in accordance with the Danish Heat Supply Act and to other consumers who are or will be connected to the distribution system.

Market Share Value of the Gas Supplier

The Market Share Value of the Gas Supplier is the sum of the Market Share Val- ues of the Metering Point for the Non-Daily Read Metering Points which the Gas Supplier supplies in a distribution area;

(16)

GLN

GLN (Global Location Number) is the number assigned to each Player in order to identify such Player in relation to communication.

GSRN

GSRN (Global Service Relation Number) is the number that must be assigned to each Metering Point (Metering Point id) and each consumer portfolio (consumer portfolio number) to ensure identification of the Metering Point or the consumer portfolio.

Gas Supplier

Gas Supplier is any natural or legal person supplying consumers with natural gas.

Meter Reading

Meter Reading is when the gas meter is read. The reading is done in whole m^3,i.e.

no decimals. At Metering Points with conversion equipment both the gas meter and the conversion equipment are read.

Metering Point

Metering Point is the actual point where the gas meter is physically located and where the natural gas is supplied to the consumer from the distribution system (place of supply).

Market Share Value of the Metering Point (expected annual consump- tion)

The Market Share Value of the Metering Point is the expected annual consump- tion of natural gas for a Non-Daily Read Metering Point as specified by the Distribu- tion Company.

Non-Daily Read Metering Point

Non-Daily Read Metering Point is a Metering Point settled between the players in accordance with the rules for non-daily metered consumption.

Terminal Date (or Date Terminal)

Terminal Date may be a Business Day and holidays etc. and is one of the following dates in connection with change of supplier, end of supply, or Relocation:

1. At 06:00 on the date on which a Gas Supplier takes over the supply to a Metering Point

2. At 6:00 on the date on which a Gas Supplier discontinues the supply to a Meter- ing Point

3. In connection with Relocation the Terminal Date is one of the following dates:

(17)

- in case of the vacating consumer’s Gas Supplier’s notification of Relocation, the date when the agreement with the Distribution Company expires as a result of the consumer’s termination of the agreement. The conditions determining when the agreement expires are laid down in the distribution conditions; or

- in case of a notification of Relocation by the incoming consumer’s Gas Sup- plier, the date when the change of supplier takes effect. The Terminal Date must be the same date on which the incoming consumer takes over the Meter- ing Point.

Daily Read Metering Point

Daily Read Metering Point is a Metering Point which is settled between the players in accordance with the rules for daily-read consumption (and where consumption data on a daily basis are available).

Validated

Validated is when consumption data have been finally Validated and adjusted, if necessary, by the Distribution Company for settlement purposes.

Non-Validated

Non-Validated is when consumption data are preliminary and have not been finally Validated by the Distribution Company.

1.6 Use of signs and decimals in messages

All values communicated in the messages must be positive unless otherwise indicated in the individual business scenarios.

Non-daily read consumption data values (MSCONS 7) must be given with a maxi- mum of three decimals. All other values must be given in integers (including the consumption reported in a base data message (UTILMD E07)).

1.7 Handling of business transactions

All players must be able to use the latest version of a given business transaction used in the business scenarios described in this document.

(18)

1.8 Deadlines for acknowledgements

The deadline for sending acknowledgements is not later than two hours after receipt of a message unless otherwise indicated in the relevant business scenario. After 20 minutes, the sender is allowed to contact the recipient to ask for an acknowledgement.

A negative CONTRL acknowledgement must be sent not later than five minutes after receipt of a message.

If a Distribution Company wants to receive CONTRL from the transmission system operator or a Gas Supplier, they must useUNB Segment ref. 0031 “ACKNOWL- EDGEMENT REQUEST” with the value “1", which results in the recipient sending CONTRL. For further information about the use of APERAK and CONTRL, see Ap- pendix Report 3 in EDI communication (Regulation F).

1.9 Codes used in EDI messages

In the EDI messages used in the business scenarios, various codes are applied. They are:

General about change of supplier

A request for a change of supplier must always be submitted to the Distribution Company by the Gas Supplier as the consumer is not entitled to do so.

Change of supplier is announced for existing Metering Points or at the initialisation of a new Metering Point.

This business scenario consists of five transactions:

 Notification of start of supply

 Notification to the previous Gas Supplier of end of supply

 Notification to the previous Gas Supplier of the consumption metered at the Non- Daily Read Metering Point.

 Announcement of Start of supply to the Public Supply Obligation Company

 Base data for Metering Point

Start condition for change of supplier

In order for the Gas Supplier to submit an electronic notification of a change of supplier for a given Metering Point ('Start of supply'), a contract must have been con- cluded with the consumer on the supply of natural gas to the relevant Metering Point from a given Terminal Date.

Steps in the scenario 'Change of supplier'

1. The consumer makes a contract with the new Gas Supplier on the supply of natural gas to a given Metering Point.

2. Following the conclusion of the contract, the new Gas Supplier sends an EDI message about start of supply (BT-001) to the Distribution Company, indicat- ing the Terminal Date requested.

In reply to the Gas Supplier's notification of start of supply, the Distribution Company sends an EDI message (BT-001) with the answer status (approved/rejected).

If the Distribution Company rejects the message, it must state one of the following reasons:

 Metering Point not identifiable

 Unauthorised Gas Supplier

(25)

 Requested Terminal Date not within deadline

 Metering Point blocked for change of supplier, eg because:

o Change of supplier has already been reported as at the Terminal Date

o if Relocation has been reported for the Metering Point before the Terminal Date for change of supplier

o Metering Point has been recorded as being closed down as at the Terminal Date.

Note that if the Distribution Company receives a notification from two Gas Sup- pliers in respect of the same Terminal Date, the Gas Supplier whose communication arrives first will be awarded the supply. Consequently, all notifications received after the one first approved are rejected.

The Gas Supplier is also entitled to cancel an approved change of supplier if the consumer exercises his right of cancellation. However, the Gas Supplier is responsible for ensuring that start of supply is requested in time for the consumer's right of cancellation in connection with distance selling to expire before the Gas Supplier's cancellation deadline expires.

The Gas Supplier also has the right to cancel an approved change of supplier for other reasons, eg if the Gas Supplier and the consumer withdraw from the contract.

If the Gas Supplier wants to cancel a change of supplier, he must do so by sending an EDI message to the Distribution Company (BT-001).

In reply to the Gas Supplier's cancellation message, the Distribution Company sends an EDI message approving or rejecting the cancellation (BT-001).

If the Distribution Company approves the cancellation of a change of suppli- er, the business scenario ends here.

If the new Gas Supplier rejects the cancellation, one of the following reasons must be stated:

 Metering Point not identifiable

 Gas Supplier not approved

 Cancellation after expiry of deadline

3. If the Distribution Company approves the request to change Supplier, the Dis- tribution Company will subsequently submit Base data as described in business process BS-203: Submission of Base data.

(26)

In cases where the road code of the installation address does not exist and thus does not appear on the Base data message, the road code will be for- warded in a new message.

Based on the consumer party’s name and the Metering Point’s address, it is the new Gas Supplier’s responsibility to manually check that the Change of Supplier has been carried out at the correct Metering Point and the correct consumer. If this is not the case, the new Gas Supplier must cancel the Change of Supplier within the cancellation period.

After having accepted the change of supplier, the Distribution Company notifies the consumer of the change of supplier and provides - as a minimum - information about Terminal Date, the new Gas Supplier, the GSRN number of the Metering Point as well as information about what the consumer should do if he wants to cancel the change of supplier.

For Non-Daily Read Metering Points the Distribution Company sends togeth- er with the information about the change of supplier a meter-reading card to the consumer, requesting him to read his meter on the Terminal Date if the time of approval for start of supply is close to the Terminal Date. If the time of approval is much earlier than the Terminal Date, the meter-reading card will be sent separately when the Terminal Date approaches.

4. When the new Gas Supplier's cancellation deadline has expired, the Distribu- tion Company implements the change of supplier as at the Terminal Date. Af- ter this has been done, a change of supplier can only be cancelled if the incoming consumer, the vacating consumer or the incoming consumer's Gas Supplier subsequently reports a Relocation for the Metering Point.

In case the initialisation of a new Metering Point the business process ends here.

5. The Distribution Company notifies the consumer of the change of supplier implemented.

6. A: The new Gas Supplier starts the supply of gas to the approved Metering Point on the Terminal Date.

B: The previous Gas Supplier stops the supply of gas on the Date Terminal for the change of supplier.

(27)

7. In the case of a Daily Read Metering Point, the previous Gas Supplier has the data necessary to settle the consumption with the consumer and sends the consumption statement to the consumer in accordance with applicable rules when the Validated metered data to be used for settlement are available.

If the previous Gas Supplier supplies gas to a Daily Read Metering Point, the business scenario ends here.

8. When the Distribution Company has received reading data for a Non-Daily Read Metering Point, the Distribution Company sends an EDI message with a statement of consumption up to the Terminal Date to the previous Gas Sup- plier (BT-007).

9. In the case of a Non-Daily Read Metering Point, the previous Gas Supplier makes a final settlement for the consumer on the basis of the consumption statement sent by the Distribution Company.

In the case of a Non-Daily Read Metering Point, the consumption statement may result in a new value for estimated annual consumption. In this case, the Distribution Company submits base data for the Metering Point to the new Gas Supplier in accordance with business scenario BS-203: Submission of base data.

The following subprocesses are only carried out in case initialisation of a new Metering Point and when the Consumer has not made an ac- tive choice of Gas Supplier.

10. If an approved Start of supply from another Gas Supplier is not available within the deadline, the Public Supplier Obligation Company will take over the delivery as per the start date. The Distribution Company informs of the Start of supply with transaction cause E06 (transfer to Public Supply Obligation Company) til the Supply Company.

11. The Distribution Company sends a message containing Base data for the Metering Point to the Public Supply Obligation Company.

Handling incorrect changes of supplier

Errors may have been committed in connection with the Gas Supplier's notification of a change of supplier.

(28)

If the error is discovered before the expiry of the Gas Supplier's cancellation period, the error can be remedied by the Gas Supplier sending a cancellation message (for the approved start of supply.

If the error is discovered after the expiry of the cancellation period, the issue is resolved by using other communication. Situations that could not have been avoided by exercising general due care are considered errors.

The Distribution Company only offers assistance in the handling of errors in connection with existing supplier relationships, ie the change of supplier that has re- sulted in the present supplier having taken over the supply. Any errors made in connection with a previous supplier taking over the supply are of no concern to the Distribution Company and must be handled by the parties involved.

The Distribution Company does not offer assistance in the handling of errors that should reasonably have been discovered earlier. The Distribution Company con- siders a change of supplier to be incorrect if the consumer vis-à-vis the Gas Sup- plier has reacted to the Distribution Company's information about an imminent change of supplier and the Gas Supplier has not reacted in time (ie by the cancellation deadline). If a consumer has made a supply agreement with a new Gas Sup- plier even though he was bound by an agreement with the previous Gas Supplier, the Distribution Company does not consider this an incorrect change of supplier.

The Gas Supplier initiating the incorrect change of supplier must also initiate procedures to handle/remedy the error. The Distribution Company only han-

dles/remedies errors if all parties involved have consented to this and such con- sent is documented.

If the Gas Supplier makes a request in the period between the expiry of the cancellation deadline and start of supply, the Distribution Company can cancel the change of supplier so that the previous Gas Supplier continues the supply of gas.

If the Gas Supplier makes a request after start of supply, the change of supplier is not cancelled retrospectively. The Distribution Company may assist in ensuring that:

 the previous Gas Supplier takes over the supply or that - if the previous Gas Supplier is opposed to this - the Public Supply Obligation Company takes over the supply instead

 a meter reading is taken so that the parties involved can indemnify the in- jured parties.
